VERSION
Version 0.056
SYNOPSIS
use HTML::DOM;
$doc = HTML::DOM->new;
$list = $doc->body->childNodes; # returns an HTML::DOM::NodeList
$list->[0]; # first node
$list->item(0); # same
$list->length; # same as scalar @$listDESCRIPTION
This implements the NodeList interface as described in the W3C's DOM standard. In addition to the methods below, you can use a node list object as an array.
This class actually only implements those node lists that are based on array references (as returned by childNodes methods). The HTML::DOM::NodeList::Magic class is used for more complex node lists that call a code ref to update themselves. This is an implementation detail though, that you shouldn't have to worry about.
OBJECT METHODS
- $list->length
-
Returns the number of items in the array.
- $list->item($index)
-
Returns item number
$index, numbered from 0. Note that you can also use$list->[$index]for short.
